65-513 6.0mm Dia. x 30.0mm FL; Plano-Convex Lens Laser V-Coat 785nm
The 65-513 is a Plano-Convex spherical lens, boasting a 6.0mm diameter and a focal length of 30.0mm, specifically designed for use with a 785nm wavelength. This lens is sourced from the renowned optical vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.
The lens is constructed from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. The lens's geometry includes a thickness of 1.01mm at the edge, gradually increasing to 1.3mm at the center, and a back focal length of 29.14mm. The inner and outer radii are both zero, indicating a uniform curvature.
The 65-513 lens features a front and back coating of EDM Las V-Coat 785, a specialized anti-reflective coating that enhances laser damage threshold and provides superior environmental stability. This coating is specifically designed for use with 785nm lasers, ensuring optimal performance and longevity.
